REST服务使用@RestController实例，输出xml/json

REST服务使用@RestController实例，输出xml/json

需要用到的服务注解

org.springframework.web.bind.annotation.RestController

　　

用到的包：java和json互转

jackson-mapper-asl #//java对象和json相互转化
jackson-databind    #spring4.1+以上都必须包含(java对象和json相互转化)

message.java

加入xml注解就支持xml,不加入只支持json

package springmvc.domain;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

//适应XML输出
@XmlRootElement(name="message")
public class Message {

	String name;
	String text;
	
	public Message(){
		
	}
	
	public Message(String name, String text) {
		super();
		this.name = name;
		this.text = text;
	}

	@XmlElement
	public String getName() {
		return name;
	}
		
	@XmlElement
	public String getText() {
		return text;
	}
	
	
}

　　

mvc/config 配置开启

package springmvc.configuration;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

//开启mvc，配置类
@Configuration
@EnableWebMvc
@ComponentScan(basePackages="springmvc")
public class HelloWorldConfiguration {

	
}

　　

初始化

package springmvc.configuration;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

//初始化
public class HelloWorldInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

	@Override
	protected Class[] getRootConfigClasses() {
		// TODO Auto-generated method stub
		return new Class[] { HelloWorldConfiguration.class };
	}

	@Override
	protected Class[] getServletConfigClasses() {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	protected String[] getServletMappings() {
		// TODO Auto-generated method stub
		return new String[]{"/"};
	}

}

　　

 

控制器：

package springmvc.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;

import springmvc.domain.Message;

@RestController
public class HelloWorldRestController {

	
	@RequestMapping(value="/hello/{player}")
	public Message message(@PathVariable String player  )
	{
		Message msg = new Message(player, "hello," + player);
		
		return msg;
		
	}
	
}
